Originally meant for internal company use only and made with a transparent shell so Apple designers could see component placement inside a finished product, this super rare Mac SE could have been yours for a startling $25,000.

The bidding's all done over at eBay, where the seller stated that the unit s fine working order, so long as you boot it up from the 800k floppy drive. No one bit though, and the $25,000 starting price couldn't elicit one bid.

Still, price issue aside, this is a remarkable collector's piece (only 10 such computers are known to exist), provided the collector has some serious coin to spend on sorta functioning PC history. [eBay via technabob]
